Patient Gender Is Associated with Distinct Patterns of Chromosomal Abnormalities and Sex Chromosome–Linked Gene-Expression Profiles in Meningiomas

Abstract excerpt

The female predominance of meningiomas has been established, but how this is affected by hormones is still under discussion. We analyzed the characteristics of meningiomas from male (n = 53) and female (n = 111) patients by interphase fluorescence in situ hybridization (iFISH). In addition, in a subgroup of 45 (12 male and 33 female) patients, tumors were hybridized with the Affymetrix U133A chip. We show a...
